As it has been discussed today in several forums, between enthusiasts, a new TECHNIC part seems to have been found among the new sets for the 2nd half.
A new steering arm variant. Look at the photos below and if you realize into the details, it turns clear that this part has differences when compared to all its known predecessors.
It doesn't seem to be, none of the illustrated below. Instead it looks like a shorter version of 32195b, with axle holes.
Steering Arm 6.5x2 with Towball Socket (on the left) and Steering Suspension Link with Arm (on the rigth)
The 'Steering Arm 6.5x2 with Towball Socket' illustrated above, had three small variations across the years (2738, 32195a and 32195b) which have been used in many sets (mainly supercars).
The part on the right shows more similarities with what we can see on the new images, but the ball joint doesn't seem very useful to connect with the actual 'Steering Gear' (x873c01) which is supposed to be found in the model, connecting the wheels to the suspension. Also the front part joining both side liftarms, doesn't fit what can be seen from the new 8297 B-model photos.
As a matter of curiosity, it seems also that "old" steering arms (the ones at left, from above) used for instance at Enzo 1:10 and Fiorano, are still used in the rear axle suspension arms of this B-model and presumably at the 8297 main model (Off Roader) too. So, it would mean a mix design in what concerns steering/suspension arms.
